Variant summary

Our verdict is Likely benign. Variant got -5 ACMG points: 0P and 5B. BP4_StrongBS1_Supporting

The NM_000041.4(APOE):c.787G>A(p.Glu263Lys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000157 in 1,581,956 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as no classification for the single variant (no stars). Synonymous variant affecting the same amino acid position (i.e. E263E) has been classified as Likely benign.

Genes affected

APOE (HGNC:613): (apolipoprotein E) The protein encoded by this gene is a major apoprotein of the chylomicron. It binds to a specific liver and peripheral cell receptor, and is essential for the normal catabolism of triglyceride-rich lipoprotein constituents. This gene maps to chromosome 19 in a cluster with the related apolipoprotein C1 and C2 genes. Mutations in this gene result in familial dysbetalipoproteinemia, or type III hyperlipoproteinemia (HLP III), in which increased plasma cholesterol and triglycerides are the consequence of impaired clearance of chylomicron and VLDL remnants.

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -5 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.016479284).

BS1

Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.000118 (18/152306) while in subpopulation EAS AF= 0.00347 (18/5180). AF 95% confidence interval is 0.00225. There are 0 homozygotes in gnomad4. There are 10 alleles in male gnomad4 subpopulation. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
